RUFUS NOBWOOD, OF BALTIMORE, MARYLAND.

lMPRQVEM ENT IN SMOKING-PIPES.

Specification forming part of Letters Patent No. 56,997, dated August 7,1866.

To all whom it may concern:

Be it known that I, Bonus Nonwoon, of the city and county of Baltimore,State of Maryland, have invented a new and useful Improvement inSmoking-Pipes; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, making a part of this specification, in WhichFigure 1 is a longitudinal section through the improved pipe whenclosed. Fig. 2 is a similar view, showing the pipe in a condition foruse. Fig. 3 is a longitudinal section through the pipe, having the stemdetached from the tobacco-tube. Fig. 4 shows the invention applied to acommon tobacco-pipe bowl.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to tobacco pipes which consist of a straight bowlfor containing the tobacco and a movable stem for forcing the tobaccotoward the open end of said bowl and discharging the ashes.

One object of my invention is to so construct such pipes that they canbe kept supplied with tobacco by introducing it at the rear end of thebowl or tube behind the lighted tobacco, for the purpose of obviatingthe necessity of relighting the tobacco every time the pipe requiresrecharging, as will be hereinafter described.

Another object of my invention is to provide for attaching a movablefiltering-stem to the neck of a common pipe-bowl, so that this stem canbe detached from the bowl at pleasure.

To enable others skilled in the art to understand my invention, 1 willdescribe its construction and operation.

In the accompanying drawings, A represents a hollow cylinder, of wood orother suitable substance, which has a hinged cap, a, with perforationsthrough it, applied to one end, and a male screw-thread, I), cut on theopposite end, for receiving a cup or ring, B, that has a hole throughits center.

0 represents the stem of the pipe, which may be made of several parts, 0d e f, and constructed'with a condensing-chamber, d, at an intermediatepoint between the mouth-piece c and perforated cup f. This cup f is madesomewhat larger in diameter than the hole through the screw-cup B, sothat when the several parts of the pipe are put together, as shown inFigs. 1 and 2, the stem cannot be withdrawn or detached from the portionA without first removing the cap B. This cup f is screwed over the endof the stem 0, and forms a chamber for receiving some suitable substancefor absorbing moisture. It also serves as a plunger or follower, forforcing the tobacco forward or toward the cap a and discharging theashes when this cap is open. Said plunger also serves for cleaning thepipe after it has been used for a considerable length of time.

The tube 0, which passes through the screwcap B, may be made taperingtoward the mouthpiece, a shown in Fig. 3, for the purpose of causing itsenlarged end to fit snugly in the hole of the cap B when said stem isdrawn out to its fullest extent.

If desirable, the stem may be made cylindrical, and a packing used at efor making a tight joint, whether the stem be in the position shown inFigs. 1 or 2.

In Fig. 4 I have represented the screw-cap applied to the neck of acommon tobacco-pipe bowl. The neck D of the bowl D is bored outstraight, so as to form a chamber, g, for receiving the plunger f. Thisplunger is applied to the stem 0, as described, for the stem 0, and isintended to serve as a means for containing an absorbent for preventingthe saliva from the mouth from moistening the tobacco in the bowl D.

By unscrewing the cap B the stem 0 can be detached from the bowl and thechamber in the stem D cleaned out at pleasure.

It will be seen from the foregoing description that the stem 0 can bedetached from the pipe A, and this pipe charged with tobacco, whetherthe tobacco which is in the pipe be ignited or not.

The great advantage of my invention is, that I make provision forintroducing fresh tobacco at the breech or rear end of the pipe withoutthe necessity of putting out the fire or discharging any of the tobaccowhich may be inthe pipe.

By this invention a person may continue smoking for a considerablelength of time with a very small pipe, and always have fresh tobacco inhis pipe.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

l. A cap, B, constructed and applied to the stem and bowl of a pipe insuch manner that the stem is connected by it to the bowl, and at willmay be disconnected or adj ustcd, substantially as and for the purposedescribed.

2. The combination of a cap, a, cap B, and a sliding stem, 0, having aplunger applied to it, substantially as described.

3. The combination of a hollow plungerstem, 0, with a pipe having adetachable cap, B, substantially as described.
